This architecturally remarkable prewar residence on fashionable Bond Street is an ingeniously designed duplex penthouse with unconnected private roof space. The romance begins on the main floor with a dramatic, light-filled living/dining room and open kitchen. The eye is drawn upward to 17-foot ceilings and a large skylight with original wood beams, and out through tall windows providing open views to the north. The chic chef’s kitchen features dual dishwashers, a warming drawer, walk-in pantry with abundant storage, and oversized honed-granite counter with seating. A spacious bedroom and full bath attend. Upstairs is the master bedroom with bath and large dressing closet, a whimsical en-suite guest room, and an open mezzanine space for an office or den.
